Transparent methodology
What the result includes—and what it does not
Built for people preparing photos for upload limits, online forms, email, websites, or social profiles.
Calculation method
- 1Each JPG, PNG, or WebP image is decoded locally and redrawn to a fresh browser canvas.
- 2The compressor searches for the highest output quality under the chosen byte limit, then progressively reduces dimensions only when quality adjustment is not enough.
- 3Batches of any size run in parallel Web Workers; results download individually or as one ZIP, and the new files omit the original embedded EXIF metadata.
Assumptions and limits
- The chosen size is a maximum, not a promise that every file will finish close to that exact byte count.
- Very small limits can require substantial dimension or quality reduction, particularly for detailed photographs.
- Browser image-codec support can vary; this tool exports WebP or JPEG and never uploads the source files.
